FOLDING FAN.

T 0 all whom it may concern.

Be it known that I, HERMAN U. OHM, a citizen of the United States of America, and a resident of Terre Haute, county of Vigo, and State of Indiana, have invented certain new and useful Improvements in Folding Fans, of which the following is a specification.

My invention relates to folding fans and has for its object the production of a fan which will be cheap and easy to construct.

To this end I have arranged the parts so that the entire fan is composed of three pieces of board (preferably card board) secured together by three eyelets or similar means.

In the accompanying drawings- Fig. 1 is an elevation of the fan in its open position, parts being broken away;

Fig. 2 shows the fan in folded position;

Fig. 3 is a section on line 33 of Fig. 2; and

Fig. 4 is a section on line l4 of Fig. 2.

The fan is composed of triangular pieces of card board 11, 12 and 13, connected together by eyelets 1 1, 15 and 16. These eyelets are secured to the part 11 near the cor ners, and these corners are preferably round ed as shown. The sides of the triangle (edges of the card board) which come together near the eyelet 14 are straight lines, but the side opposite the eyelet 14 is the are of a circle with the point 14 as a center.

The eyelet 14 connects all three parts together, and is the pivot on which the parts Specification of Letters Patent. Patented June 20, 1922. Application filed June 9, 1921.

12 and 13 move with respect to the part 11. The eyelet 15 connects part 12 to part 11, and eyelet 16 connects part 18 to part 11.

The parts 11, 12 and 13 are preferably of the same dimensions and alike in all particulars except that part 12 has therein a slot 17, and the part 13 has a slot 18. These slots are arcs of a circle of which the point 1 1 is the center, and their radii are the distances the eyelets 15 and 16 are from the center 14. The eyelet 15 extends through the slot 17 and the eyelet 16 extends through the slot 18. The fan is opened and closed by causing the parts 12 and 13 to move on the pivot 14, and the slots 17 and 18 to slide "on the eyelets 15 and 16.

WVhat I claim is:

1. A fan composed of three triangular pieces of cardboard connected together by three eyelets, one of said eyelets serving as a pivot connecting the three parts together and the other two eyelets serving to permit two of said pieces of card board to be moved independently with respect to the third piece.

2. In a fan, a triangular piece of card board, eyelets secured to said card board near its corners, andtwo other pieces of card board pivoted upon one of said eyelets, each of said other pieces having therein an arc-shaped slot arranged to engage and slide upon one of the other eyelets.
